论文摘要
量子计算过程中不可避免地存在变质现象。因此，例如，通过动态去耦，量子误差校正代码（QECC）等通过动态抑制作用的动态抑制对于准确执行已知或已开发的量子算法至关重要。尽管这种动态的零噪声策略非常适合我们对量子计算未来的期望，但鉴于现状，我们已经根据相反的噪声策略来推出了15年以上自我保护的量子算法。在这里，我们提出了自我保护的量子模拟对大型经典噪声的免疫。因此，对于读数，我们将常规量子相估计概括为具有经典噪声的升级版本。
The decoherence phenomenon inevitably exists in quantum computing processes. Consequently, dynamic suppression of decoherence for instance via dynamical decoupling, quantum error correction codes (QECC) etc. is crucial in accurately executing known or to-be-developed quantum algorithms. While this dynamic zero noise strategy well fits into our expectations for the future of quantum computing, given the status quo, we have launched self-protected quantum algorithms for over 15 years based on the opposite living-with-noise strategy. Here we propose self-protected quantum simulations immune to a large class of classical noise. Accordingly, for readout we generalize the conventional quantum phase estimation to its upgraded version in the presence of classical noise.
